Can you tell which twin was conceived first?
The most accurate way to tell if twins are identical is through a DNA test. This can only be done after your babies are born. The placenta could also provide clues. If your first ultrasound scan is done before 14 weeks, it should be possible to tell accurately what kind of placenta your twins have.
What is a super twin baby?
Superfetation refers to fertilization and implantation of a second conception during pregnancy. Her twins are DZ or fraternal twins, which occurs when two eggs are released at a single ovulation and are fertilized by two different sperm, according to Twins Research Australia.
Can you ovulate twice in one cycle a week apart?
Only one ovulation can happen per cycle. You can, however, ovulate two (or more) eggs at the same time.

But having two separate eggs released at different times within the same cycle doesn’t happen.
Can you be pregnant with two babies with different due dates?

An identical twin pregnancy occurs when the fertilized egg splits. Sometimes, a single embryo splits after it’s been fertilized, resulting in identical twins. Because both cells come from the exact same egg cell and sperm cell, identical twins will have the same DNA, the same sex, and a nearly identical appearance.
Can two fetuses be conceived at the same time?
Although two fetuses develop simultaneously in superfetation, they differ in maturity, having been conceived days or even weeks apart. Superfetation is observed in animal reproduction, but it is exceedingly rare in humans.
Is it safe to give birth to twins 3 weeks apart?
As there is a higher rate of twins being born at less than 37 weeks, this increases the risk for the younger twin. Most of the verified cases have been with twins that are only 10 days to three weeks apart, and the reported cases were usually safely delivered.
Can twins be discordant in size and development?
In another case, the twins were significantly discordant in size and development at birth, according to the study. In fact, when twins are markedly different in size when they are born, this may be due to different gestational ages because they are super twins that were conceived at different times.
